Default vf48 on a 04 sti?

hey i have a 04 with a blown vf39 turbo... i was wondering if a vf48 turbo(08 sti) will fit onto my car 100% bolt on with out changing any oil/water lines around and keeping my cobb downpipe.. i know the vf43 will work but after readind around it looks like the vf 48 can make a little more power.... i have full 3 inch exhaust equal lenght header and a intake and accesport. im looking to buy a brand new vf48 for around 1200 does that seem stupid to you guys with the other turbo choices out there but remember im only looking for at most 315 whp/tq..

yea ive been on blouchturbo the only two they have listed for the sti seem like there too much for what i want.. Subaru WRX/STi 18G-XT Turbocharger is a 430hp turbo and with that i would probably have to do injecters/fuel pump im guessing. can anyone sugest a turbo that will run on stock fuel/injectors hit around 320whp and will be as reliable as a vf43/48 for around the same price?? and can someone verify that a vf48 will work on a 04 sti?

You used to be able to get brand new VF48's for $700 here. $1200 is ludicrous! I paid I think $650 a while back for a brand new one from a member that was banned on here

There are legit vendors that sell them for under $800 I believe...

That said, buy a used VF48/43 or if cash were really tight... another 39, as those are a dime a dozen.

You can always get your turbo rebuilt, remanufactured, or just upgraded as long as the core is sound. It does not have to be rebuildable.

BNR does this service.

I'm very much looking into buying a blown VF48, getting it upgraded and replacing my current VF48 on my car. Blown VF48 ~$100 + 20G/TD05 Uograde $800= ~$900. Selling my old VF48 with under 3K miles for ~$600 only is a $300 difference to get a new 20G turbo. Always an option for you.

What help do you need? Find a turbo that you can afford.. factoring in that you also own an accessport, so you need to have a map available too (a hidden cost if you will).

That said, find a used or godo low cost new OE VF series turbo which are around... Or see if there is a pre-made map for your mods with a non VF turbo avail you can download and run.

For a new VF, try P&L Motorsports or AJW Performance. Both vendors on this board that have or had sold those turbos. P&L used to sell them cheap! Like $600 cheap for new VF48's.

Fuel pump is a good safety measure in general for the STi.

Injectors could depends on many factors, especially since the non VF turbos suggested here can hold power up top better, and can run higher boost pressures, that larger injectors may be needed, depending on how far you want to push things.. e.g. run up to 18psi, and taper towards redline, you may not need injectors. Run 22psi, and taper to 18-16psi at redline on a non-VF and you may want to run injectors if you want to keep your engine.

Ultimately, your tuner will tell you what is needed and what he/she is used to working with.

Just go through the exhaust section through the isles. They are not listed as studs I believe. And the workers there will and are generally useless for anything other than getting a wiper blade replaced.
